I've found that a lot of rechargeable vibrators have totally different patterns on charging lights, like some will flash when charging and then stay on when charged, or show red when charging and turn green when done.
I don't know if I'm just someone with a terrible memory and too many toys, or if it would be helpful to have what each light means in the description of the toys, since it would just be one line, something like "X speeds, X patterns, lights when charging, lights when charged." At the moment I'm combing through reviews trying to find someone who mentions it for a lot of them!
Is this something that would be useful for anyone else, or should I just make a note of them for myself?
